A Census of Blue Stragglers in Gaia DR2 Open Clusters as a Test of Population Synthesis and Mass Transfer Physics [PDF]
, 2021 We use photometry and proper motions from Gaia DR2 to determine the blue straggler star (BSS) populations of 16 old (1–10 Gyr), nearby (d < 3500 pc) open clusters.

Astrophysical Journal, 2022 Blue stragglers (BSs) in different regions (e.g., two sequences) of the color–magnitude diagram (CMD) have been suggested to provide a strong constraint on the origin of BSs in globular clusters (GCs).

Connecting the Local Stellar Halo and Its Dark Matter Density to Dwarf Galaxies via Blue Stragglers [PDF]
Astrophysical Journal, 2020 The Gaia H-R diagram shows the presence of apparently young stars at high tangential velocities. Using a simple analytical model, I show that these stars are likely to be blue stragglers.

The origin of the two populations of blue stragglers in M30 [PDF]
Astronomy & Astrophysics, 2019 We analyze the position of the two populations of blue stragglers in the globular cluster M30 in the Hertzsprung–Russell diagram. Both populations of blue stragglers are brighter than the cluster’s turn-off, but one population, the blue blue-stragglers ...

Variable Blue Straggler Stars in the Open Cluster NGC 6819 Observed in the Kepler “Superstamp” Field
The Astronomical Journal, 2023 NGC 6819 is an open cluster of age 2.4 Gyr that was in the NASA Kepler spacecraft’s field of view from 2009 to 2013. The central part of the cluster was observed in a 200 × 200 pixel “superstamp” during these four years in 30 minute cadence photometry ...

The Astrophysical Journal, 2023 We present the results of our Hubble Space Telescope far-ultraviolet survey of the blue lurkers (BLs) in M67. We find evidence for two white dwarf (WD) companions among the BLs that are indicative of mass transfer from an evolved companion, one in WOCS ...

BLUE STRAGGLERS AFTER THE MAIN SEQUENCE [PDF]
The Astrophysical Journal, 2009 We study the post-main sequence evolution of products of collisions between main sequence stars (blue stragglers), with particular interest paid to the horizontal branch and asymptotic giant branch phases. We found that the blue straggler progeny populate the colour-magnitude diagram slightly blueward of the red giant branch and between 0.2 and 1 ...

Primordial binary evolution and blue stragglers [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractBlue stragglers have been found in all populations. They are important in both stellar evolution and stellar population synthesis. Much evidence shows that blue stragglers are relevant to primordial binaries. Here, we summarize the links between binary evolution and blue stragglers, describe the characteristics of blue stragglers originating ...
